Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008920, here are decompositions:

7 + 1008913 = 1008920
19 + 1008901 = 1008920
61 + 1008859 = 1008920
67 + 1008853 = 1008920
103 + 1008817 = 1008920
127 + 1008793 = 1008920
139 + 1008781 = 1008920
307 + 1008613 = 1008920

Showing the first eight; more decompositions exist.
